Trina - you didn't sound at all like you were looking for anything and just by the fact that she OFFERED you a new puppy at the time you told her about Lexxie says to me she
knows she sold you a dog with medical issues

She may have said that out of guilt or to pacify you and probably never had any intention to help you. Ignoring you & Lexxie during the last few years says it all.
When it boils down - it's all about the money with some breeders. They can quote all the bible verse they want - but actions, ethics and reputation speak way louder...and it sounds like she just showed you how ethical she is....or should I say ISN'T.
Funny how some breeders can play so dumb and act like they've never heard of certain conditions (hydrocephalus). My Chanels breeder did the same thing when I told her Chanel had coccidia 4 days after bringing her home - she claimed she'd never heard of it too - yeah right
You can go 2 ways - never deal with her againm, do a review here and hope people see it ...or push her more and see if she makes an attempt to make it right - I don't see that happening though. I'm sorry she didn't care enough to help you thru the loss of your pretty girl - that really SUCKS!
(I'm sorry for your loss again) Rest in peace Lexxie.
